IMPROVEMENT IN THRASHlNG-MACHINES.

Specification forming part of Letters Patent No.

176,463, dated April 25, 1876; application filed August 30, 1875.

To all whom it may concern:

Be it known that I, VICTOR FAVIER, of the city of Perwez, in the Province of Brabant and Kingdom of Belgium, have invented new and useful Improvements in Beaters for- Thrashing-Machines, of which the following is a specification My invention consists in constructing the heaters in such a manner as to shake the ears of the grain violently to and fro in a rapid manner without bruising or crushing such grain or the straw, and so arranged that the ear and but a small portion of thestraw of the grain are exposed to the action of the heaters. To effect this I construct the beaters of elliptical form in cross-section covered with zinc, sheet-iron, or other suitable material, thereby giving them a smooth surface.

In the accompanying drawings, Figure 1 is a vertical transverse section of two heaters constructed according to my invention. Fig. 2 is a side elevation of the same, and Figs. 3 and 4 are similar views to Figs. I and 2 of a slight modification of the same.

A A are the heaters, consisting of the two end pieces a, and one or more inner arms, a connected together by transverse bars or braces a bolted or otherwise affixed to the arms a and end pieces (t the whole being coveredwith zinc or sheet-iron, or other suitable material. The end pieces and arms are of elliptical form, or of such a form that when the frame is covered the heaters are elliptical in cross-section. The end pieces a and arms a have apertures formed in their centers for the purpose of mounting them upon the shafts B B, to which they are rigidly bolted or otherwise affixed. The heaters A A are mounted upon the shafts B B in such a manner that when the beater A is in a vertical position the heater A will be in a horizontal position, and

vice versa, during their revolution. The shafts B B carry each a cog-Wheel, O O, of equal diameter, and having'each an equal number of teeth or cogs. These two wheels 0 G mesh into each other, thus connecting the two beaters A A together.

I prefer to use cog-wheels of such a size,

and having-a sufficient number of teeth to 'im' part to the heaters A A from four hundred to four hundred and fifty revolutions per minute, according to the nature of the grain to be thrashed.

, Power is applied to the heaters A A from any desired and suitable motor by means of a pulley carried by one of the shafts B B. The grain to be thrashed is presented to the action of the heaters in such a manner'that the ears and a very small portion of the straw or stalk only are subjected to the shaking or whipping action ofthe heaters AA. From four to five inches are found to be sufficient. The action upon the grain by the heaters A A is very effective, as with a speed of. four hundred revolutions per minute the ears are subjected to a violent reciprocating shaking sixteen hundred times, the ears being whipped up and down against the heaters without either crushing or bruising the the grain or breaking the stalks or straw. The surface of the heaters being very smooth the dragging or sucking in of the straw is also obviated, and the heaters A A acting only on the ears of the grain a great saving of power is effected while the grain is thoroughly and effectually shaken out of the ears.

Instead of constructing the heaters A A as described above they may be arranged and constructed as shown by Figs. 3 and 4, in which a a are the arms of the form, as shown, having their centers enlarged and provided with apertures for the purpose of mounting them upon the shafts B B. The arms a are. connected together by transverse bars or braces a and are covered by zinc or sheetirou, or other suitable material, on one side only, as shown. Thus, instead of forming a perfect ellipse in cross-section, which would be the case when entirely covered by the sheet metal, they form four heaters, the operation and action of which are similar to the two beaters A A, above described.

Having described my invention, What I claim, and desire to secure by Letters Patent, 1s

In a thrashing-machine, the combination of two heaters, A A, arranged to operate as de- In presence of JNo. WILsoN,
